How to use

Wipe the sponge across the board surface to remove fresh dry-erase marker ink and light stains. Apply even pressure and rub in a circular or linear motion until marks are removed.

Do not use abrasive scrubbing motions that could damage the board coating.

Combine occasional cleaning with an appropriate non-abrasive whiteboard cleaner for stubborn marks or ghosting, and follow the whiteboard manufacturer's maintenance guidance to preserve the writing surface.
